s, the polecat has a shorter, more compact body, a more powerfully built skull and dentition, and is less agile in its movements.

It is much less territorial than other Mustelids, with animals of the same sex frequently sharing home ranges. Like other Mustelids, the European polecat is polygamous, though pregnancy occurs directly after mating, with no induced ovulation. It usually gives birth in early summer to litters consisting of 5-10 kits, which become independent at the age of 2–3 months. The European polecat feeds on small rodent

, it is likely that the European polecat was first domesticated in these regions.

In size and proportions, the ferret is similar to the European polecat, to the point that dark coloured ferrets are almost indistinguishable from their wild cousins, though the ferret's skull has a smaller cranial volume, and has a narrower postorbital constriction. Compared to the European polecat, the ferret has a much smaller brain, though this comparison has not been made with Mediterranean polecats, from which ferrets likely derive. The theory of a Mediterranean origin is further strengthened by the fact that the ferret is less tolerant of cold than northern polecat subspecies. The ferret is also more fertile than the polecat, producing two or more litters annually, as opposed to just one. Unlike other subspecies, which are largely solitary, the ferret will readily live in social groups. The ferret is also slower in all its movements than the polecat, and hardly ever makes any use of its anal scent glands. Overall, the ferret represents a neotenous

 is known among polecats, but specimens exhibiting this are likely the products of polecat-mink hybridisation.

Fur

The winter fur of the European polecat is brownish-black or blackish-brown, the intensity of which is determined by the colour of the long guard hairs. On the back and flanks, the dark tone is brightened by bright whitish-yellowish, sometimes yellowish-greyish underfur which shows through. The lightly coloured underfur is not equally visible on different parts of the body. On the back and hind quarters, the underfur is almost completely covered by the dark guard hairs. On the flanks however, the lightening is well defined, and contrast sharply with the general tone of the back. The throat, lower neck, chest and abdomen are black or blackish-brown. The limbs are pure black or black with brown tints, while the tail is black or blackish-brown, completely lacking light underfur. The area around and between the eyes is black-brown, with a longitudinal stripe of similar colour along the top of the nose. The ears are dark brown and edged with white. The summer fur is short, sparse and coarse. It is greyer, duller and lacking in the lustre of the winter fur. The underfur is more weakly developed in the summer fur, and has a brownish-grey or rusty-grey colour. The polecat is a good swimmer, but its fur is not as well insulated against cold water as the American mink
American Mink
The American mink is a semi-aquatic species of Mustelid native to North America, though human intervention has expanded its range to many parts of Europe and South America.

s. In typical erythristic individuals, the underfur is usually bright reddish. The guard hairs on the trunk are bright reddish or reddish brown. Black guard hairs are absent on the lower body and head. In some rare cases, the guard hairs are so light that they are almost indistinguishable from the pale-yellow underfur. In these cases, the whole animal is very light pale golden-yellow colour.

Social and territorial behaviours

Unlike the steppe polecat, the European polecat has a much more settled way of life with definite home ranges. The characteristics of polecat home ranges vary according to season, habitat, sex and social status. Breeding females settle in discreet areas, whereas breeding males and dispersing juveniles have more fluid ranges, being more mobile. It is typical for males to have larger territories than females. Each polecat uses several den sites distributed throughout its territory. Occasionally, abandoned European badger or red fox
Red Fox
The red fox is the largest of the true foxes, as well as being the most geographically spread member of the Carnivora, being distributed across the entire northern hemisphere from the Arctic Circle to North Africa, Central America, and the steppes of Asia...

 burrows are used. Rabbit warrens are often areas of intense polecat activity. In winter, the polecat may use farm buildings or haystacks as daytime resting sites. The polecat is not as territorial as other small mustelids, having been known to share territories with other members of the same sex. There is little evidence of polecats marking their territories. Like other mustelids, the polecat is a silent animal, though it will growl fiercely when angered, and squeak when distressed. It also emits a low, mewling cry to its mate or offspring.

Reproduction and development

The European polecat is a seasonal breeder, with no courtship rituals. During the mating season, the male grabs the female by the neck and drags her about in order to stimulate ovulation
Ovulation

At birth, the kits weigh 9-10 grams and measure 55–70 mm in body length, and are blind and deaf. At the age of one week, the kits are covered in silky, white fur, which is replaced with a cinnamon brown-greyish woolly coat at the age of 3–4 weeks. Weaning

This killing method is instinctive, but perfected with practice. The polecat sometimes caches its food, particularly during seasonal gluts of frogs and toads. Sometimes, the polecat does not kill these, but bites them at the base of the skull, thus paralyzing them and keeping them fresh for later consumption.

, or as late as the fourteenth century. It is currently impossible to distinguish pure polecats from hybrids through DNA analysis, as the two forms are too closely related and inter-mixed to be separated through modern genetic methods. Crossbreeds between the two animals typically have a distinct white throat patch, white feet and white hairs interspersed among the fur. Typically, first generation crossbreeds between polecats and ferrets develop their wild parent's fear of humans if left with their mother during the critical socialisation period between 7½ and 8½ weeks of age. Occasionally, supposed ferret-polecat crossbreeds are advertised as superior to pure ferrets for the purposes of rabbiting

, producing offspring termed khor'-tumak by furriers and khonorik by fanciers. Such hybridisation is very rare in the wild, and typically only occurs where European mink are declining. Polecat-mink hybrids have a poorly defined facial mask, have yellow fur on the ears, grey-yellow underfur and long, dark brown guard hairs. They are fairly large, with males attaining the peak sizes known for European polecats (weighing 1,120-1,746 g and measuring 41–47 cm in length) and females being much larger than female European minks (weighing 742 g and measuring 37 cm in length). The majority of polecat-mink hybrids have skulls bearing greater similarities to those of polecats than to minks. Hybrids can swim well like minks and burrow for food like polecats. They are very difficult to tame and breed, as males are sterile

During the summer period, the diet of wild polecat-mink hybrids is more similar to that of the mink than to the polecat, as they feed predominantly on frogs. During the winter, their diet overlaps more with that of the polecat, and will eat a larger proportion of rodents than in the summer, though they still rely heavily on frogs and rarely scavenge off of ungulate carcasses as the polecat does.

The species held an important place in Scotland's fur markets ; the annual Dumfries Fur Fair (1816–1874) sold 400 polecat pelts in 1829 and 600 in 1831. The following year, a contemporary account described polecat skins as "a drug on the market". In 1856, the number of sold pelts decreased to 240, 168 in 1860, 12 in 1866 and none in 1869.

: "Out of my door, you witch, you hag, you baggage, you polecat, you runyon!". In some rural areas, the belief persists that the polecat chews off the ears of sleeping sheep and can paralyse or kill men by jumping on them from behind and biting their necks. However, in some regions, it was widely believed among farmers that allowing a polecat to nest in a chicken coop would ensure that the animal would not kill the poultry out of gratitude, and instead kill vermin. Cases in which polecats did kill poultry were attributed to animals which were guests at other farms. In Wales, it was widely believed that polecats migrated in large numbers every spring to the great peat bog of Tregaron
